Abstract: 509,967. Fluid-actuated valves. JUNKERS FLUGZEUG - UND - MOTORENWERKE AKT.- GES. Oct. 5, 1938, No. 28901. Convention date, Oct. 9, 1937. [Class 135] A valve device, particularly for use on aircraft for maintaining a constant relative proportion between the amounts of fluid supplied to branch pipes 2, 3 by a supply conduit 1 comprises a cylindrical member 24 with a series of radial ports 26 adapted to connect the inlet 1 with two narrow axial passages 32, 33 leading to chambers 28, 29 in turn connected to the branch conduits. The end faces of the members 24 co-operate with conical seats 30, 31 on the end walls of the chambers 28, 29 to form throttling points so that as the member moves in response to variations in flow a throttling action is set up in one or other conduit to restore the balance. Bye-pass passages may be provided connecting the main inlet with the branch passages and fitted with non-return valves 36, 37 to permit an unregulated return flow. The Specification, as open to inspection under Sect. 91, describes a construction in which a slide valve in each branch conduit is actuated by a spring-loaded double-acting piston subject to the throat and full-bore pressure of a Venturi pipe inserted in each branch. In a modification of this form two slide valves are operated by a single piston subject to the throat pressures in two Venturi tubes. In another form spring- loaded spherical valves in each conduit are moved by rush of fluid into a more restricted part of the conduit. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to circular knitting machines
IPC: D04B9/10
Filed: 1932-10-17
Abstract: 408,942. Circular knitting-machines. GRIEVE & CO., Ltd., T., and GRIEVE, T. S., Queen Street, Leicester. Oct. 17, 1932, No. 28969. [Class 74 (ii).] A superposed needle cylinder machine has auxiliary transfer cams in both cam boxes acting upon differentiated sliders under control of an auxiliary pattern device. The ordinary transfer cams may also function for patterning. An auxiliary cam 2 moves radially from an outer inoperative position to various inner operative positions the sliders operated on being determined by the depths of recesses 8. An ordinary transfer cam 6 movable radially, acts on the transfer butts 10 which differ among themselves in length. These two cams operate in conjunction with a fixed cam 11 which engages the knitting butts 12. This causes those sliders selected to engage a dividing cam D which deflects them outwards to liberate the upper hooks of the needles. An auxiliary transfer cam 13 and an ordinary transfer cam 14, also movable radially, act on knitting butts 17 and transfer butts 18, of variable length. A cam disposed at a lower level than usual, acts on the tails of sliders associated with instep needles and elevates these during heel and toe knitting. The tails of the sliders for the heel and toe needles have recesses so as to avoid engagement with this cam. The transfer cams are movable into their working positions against the action of springs 2<a>, 6<a>, 13<a>, 14<a>. Bits 19<a>, 19<b>, on an auxiliary drum 19 act on levers 29, 35 and thus operate the top auxiliary and main cams through levers 27, 25, and 34, 32 fast on rockshafts 26 and 36, links 24 and 31 and bell crank levers 20 and 30. Cam bits 19<c> act on a lever 43. This actuates a lever 41, loose on a rockshaft 33, which engages a lever 40 fast on a rockshaft 39 on the other end of which a lever 37 operates the cam 13. Bits 19<d> act on a lever 49 which actuates a rockshaft 46, through a lever 47. A lever 44, fast on the rockshaft, operates the cam 14, levers 51 and 58, acting on groups of levers 29, 41, 47 and 34 respectively enable all cams to be operated by cam bits 50<a>, 50b, on the main controlling drum 50. The auxiliary drum 19 is rocked by means of cams on the cylinder driving gear 67, and pawl and ratchet mechanism. When half-round pattern effects are produced the drum 19 is moved axially by a plunger 80, operated by cam bits 88 on the drum 50, through a bell crank lever 84. A bluff, operated by the main drum, can render the pawl 73 inoperative for predetermined intervals, with the transfer cams in an inoperative position. Specification 15008/00, [Class 74], is referred to.

Title: Device for automatic discharge of rockets
IPC: F41A9/38
Filed: 1948-11-08
Abstract: 663,651. Rocket-discharge apparatus. AKTIEBOLAGET BOFORS. Nov. 8, 1948. [Nov. 7, 1947] No. 28997/48. Class 92 (ii). A magazine device for the automatic discharge of rockets comprises a magazine 3 for receiving and advancing to a discharge position a plurality of cases 2 each containing a rocket, stop means 8 for controlling the ejection of the cases, a discharge tube 7 tapering in a direction away from the magazine, and a member 17 mounted in the tube 7 and serving, when tripped by a discharged rocket, to arrest the advance of the rockets in the magazine. In the construction shown the rockets in the magazine are advanced by a spring-controlled lazy tongs device 4, and the stop means 8 consists of two pivoted elements fitted with rollers 9. A shaft 11 has an arm 15 adapted to be moved by a nose 16 on the member 17, which is pivoted, and on the shaft are levers 10 each operatively connected to the stop means as shown in Fig. 5. Springs tend to rotate the shaft 11 clockwise but such movement is normally prevented by a catch, not shown. Operation. The first rocket upon being fired from its case 2 trips plate 17 and so rocks shaft 11 anticlockwise. This moves the stops 8 to a rocket-retaining position and enables the catch to move to an inoperative position. Subsequently the springs associated with shaft 11 assert themselves thus removing the stops 8 and the feeding of the rockets to the discharge position. The feed is continuous whether the rockets are discharged or not, and the stops 8 move to and from the rocketretaining position upon the passage of any rocket down the discharge tube. The tapering of the magazine end of the tube 7 enables firing of the rockets to take place before they actually reach the discharge position.

Title: Improvements in or relating to optical filters
Inventor: CHARNOCK JOHN
IPC: G02B5/28
Filed: 1953-10-26
Abstract: An infra-red optical filter comprising a coating of germanium on a transparent base is produced by heating the base to 200  DEG C. or more while the germanium is being deposited by evaporation-deposition. In this way a thick coating (e.g. 0.001 inch) is produced with less tendency to flake.  Preferably the deposition is in two or more stages and the germanium is evaporated from an electrically conductive boat of tantalum, molybdenum or carbon. Carbon is preferred as the germanium alloys with the metals if the boat is used a few times.  The base may be of glass plate, rock salt, synthetic sapphire or periclase or of "Kodial" or "Pyrex" (Registered Trade Marks) glass.  The latter are particularly suitable with a thermal expansion coefficient similar to germanium.  If the germanium is evaporated upwards the base may be heated with an electrically heated copper slug.  After formation of the coating, blooming may be effected with zinc sulphide or metallic selenium.
